Vulkan是新一代图形和计算API，它提供了对现代gpu的高效、跨平台访问，这些gpu用于从pc和控制台到移动电话和嵌入式平台的各种设备。，

如何编译

Build for Linux

在 Debian, Ubuntu 上 安装 vulkan sdk:

sudo apt instal libvulkan-dev

下载 Vulkan SDK

# download vulkan sdk
$ wget https://sdk.lunarg.com/sdk/download/1.1.114.0/linux/vulkansdk-linux-x86_64-1.1.114.0.tar.gz?Human=true -O vulkansdk-linux-x86_64-1.1.114.0.tar.gz
$ tar -xf vulkansdk-linux-x86_64-1.1.114.0.tar.gz

# setup env
$ export VULKAN_SDK=`pwd`/1.1.114.0/x86_64

$ cd <tengine-lite-root-dir>
$ mkdir -p build-linux-vulkan
$ cd build-linux-vulkan
$ cmake -DTENGINE_ENABLE_VULKAN=ON ..

$ make -j4
$ make install

Build Android Library

$ cd <tengine-lite-root-dir>
$ mkdir -p build-android-aarch64-vulkan
$ cd build-android-aarch64-vulkan
$ cmake -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build/cmake/android.toolchain.cmake \
    -DANDROID_ABI="arm64-v8a" \
    -DANDROID_PLATFORM=android-24 -DTENGINE_ENABLE_VULKAN=ON ..

$ make -j4
$ make install
